The Complete Guide to Jaw Crushers
What is a Jaw Crusher?
A jaw crusher is a primary crushing machine used in mining, quarrying, and recycling applications. As one of the most essential rock crusher types, jaw crushers are designed to break down large stones and ores into smaller, more manageable pieces through compressive force between a fixed stationary jaw and a moving adjustable jaw.
GELEN, as a leading manufacturer among jaw crusher manufacturers, offers a wide range of jaw crushers suitable for various applications and production requirements. Our jaw crusher machine models come in different jaw crusher sizes to handle capacities from a few tons per hour to large-scale operations.
How Jaw Crushers Work
The crushing process in a jaw crusher begins when material enters the crushing chamber through the top opening as the jaws open. The moving jaw then compresses the material against the stationary jaw, creating the necessary force for size reduction.
Key components of our jaw crushers include:
- Jaw plates - Replaceable manganese steel surfaces that contact the material
- Toggle plate - Safety mechanism that protects the crusher from damage
- Overhead eccentric shaft - Provides the crushing motion
- Crushing chamber - Designed for optimal material flow and reduction
The material is crushed until small enough to pass through the bottom opening, achieving the desired size for further processing.
Types of Jaw Crushers
GELEN manufactures several crusher types to meet diverse operational needs:
1. Single-Toggle Jaw Crushers
Our single-toggle jaw crusher machine features a simple design with one moving jaw, ideal for:
- High capacity primary crushing
- Medium-hard to hard materials
- Applications requiring increasing productivity
2. Double-Toggle Jaw Crushers
The double toggles design provides:
- Higher crushing force for tougher materials
- Reduced wear on jaw plates
- More uniform product size
3. Mobile Jaw Crushers
Our mobile jaw crusher solutions offer:
- Complete crushing plants on wheels
- Quick setup and relocation
- Ideal for temporary sites and contract crushing
